| Abstract | |
The development of farming goats in Brazil, and the need of sanitary control of these flocks, justify the study of tuberculin test evaluation in goats. Using cut-off points established by Silva et al. (2006), 600 goats from Minas Gerais, Paraná, Pernambuco, Paraíba and São Paulo states were evaluated. According to Comparative Cervical Test values, 60 goats were selected, and submitted to clinical exams, euthanized and materials collected for microbiologycal, histopathologycal and genetic typing. Out of the 36 positive goats, 27 (72%) had isolation of micobacteria classified like Mycobaterium tuberculosis complex. Focus of tuberculosis were identified in São Paulo, Minas Gerais and Paraíba states. Besides isolation of the M. tuberculosis complex micobacteria, other bacterias like M. kansasii, M. flavescens, M. avium, M. florentinum lentiflavum simiae complex, Corynebacterium pseudotuberculosis and C. bovis were identified in some animals. In one case, isolation of C. bovis occurred together with micobacteria of the M. tuberculosis complex. The macroscopic and histopathological lesions did not discriminate infection for C. bovis or of the M. tuberculosis complex micobateria. The bacteriological, histopathological and genetic typing results validate the use of cut-off points established by Silva et al. (2006), in the Cervical Comparative Test for diagnosis of tuberculosis in goats. (AU) | |
